Programs & Examples On #Jscrollpane

The Easiest way to implement scrollbar using java swing is as below :

1. Navigate to Design view
2. right click on textArea
3. Select surround with JScrollPane

This will do it:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

Ameritrade also offers an API, as long as you have an Ameritrade account: http://www.tdameritrade.com/tradingtools/partnertools/api_dev.html

[System.Diagnostics.FileVersionInfo]::GetVersionInfo("Path\To\File.dll")

If you don't want hashes and just the first lines (subject lines):

git log --pretty=format:%s

Try this out.

function loadlink(){
    $('#links').load('test.php',function () {
         $(this).unwrap();
    });
}

loadlink(); // This will run on page load
setInterval(function(){
    loadlink() // this will run after every 5 seconds
}, 5000);

Hope this helps.

I was getting this error 2013 and none of the above preference changes did anything to fix the problem. I restarted mysql service and the problem went away.

If you'd like to initialize the array to values other than 0, with gcc you can do:

int array[1024] = { [ 0 ... 1023 ] = -1 };

This is a GNU extension of C99 Designated Initializers. In older GCC, you may need to use -std=gnu99 to compile your code.

You can use argv npm module (install it by running npm install argv --save) for getting params in your webpack.config.js file and as for production you use -p flag "build": "webpack -p", you can add condition in webpack.config.js file like below

plugins: [
    new webpack.DefinePlugin({
        'process.env':{
            'NODE_ENV': argv.p ? JSON.stringify('production') : JSON.stringify('development')
        }
    })
]

And thats it.

Very often this error appears if you use incompatible versions of Selenium and ChromeDriver.

Selenium 3.0.1 for Maven project:

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.0.1</version>
    </dependency>

ChromeDriver 2.27: https://sites.google.com/a/chromium.org/chromedriver/downloads

eventcreate2 allows you to create custom logs, where eventcreate does not.

The other solution works great for square images. Here is a solution that will work for an image of any dimension. The canvas will always fit the image rather than the other solution which may cause portions of the image to be cropped off.

var canvas;

var angleInDegrees=0;

var image=document.createElement("img");
image.onload=function(){

    drawRotated(0);
}
image.src="http://greekgear.files.wordpress.com/2011/07/bob-barker.jpg";

$("#clockwise").click(function(){ 
    angleInDegrees+=90 % 360;
    drawRotated(angleInDegrees);
});

$("#counterclockwise").click(function(){ 
    if(angleInDegrees == 0)
        angleInDegrees = 270;
    else
        angleInDegrees-=90 % 360;
    drawRotated(angleInDegrees);
});

function drawRotated(degrees){
    if(canvas) document.body.removeChild(canvas);

    canvas = document.createElement("canvas");
    var ctx=canvas.getContext("2d");
    canvas.style.width="20%";

    if(degrees == 90 || degrees == 270) {
        canvas.width = image.height;
        canvas.height = image.width;
    } else {
        canvas.width = image.width;
        canvas.height = image.height;
    }

    ctx.clearRect(0,0,canvas.width,canvas.height);
    if(degrees == 90 || degrees == 270) {
        ctx.translate(image.height/2,image.width/2);
    } else {
        ctx.translate(image.width/2,image.height/2);
   }
    ctx.rotate(degrees*Math.PI/180);
    ctx.drawImage(image,-image.width/2,-image.height/2);

    document.body.appendChild(canvas);
}

I will give my answer from a competitive programming(cp) perspective, but it applies to other domains as well.

Many a times while doing cp, constraints are quite large.

For example : I had a question with a variables N, M, Q such that 1 = N, M, Q < 10^5.

The mistake I was making was I declared a 2D integer array of size 10000 x 10000 in C++ and struggled with the SIGABRT error at Codechef for almost 2 days.

Now, if we calculate :

Typical size of an integer : 4 bytes

No. of cells in our array : 10000 x 10000

Total size (in bytes) : 400000000 bytes = 4*10^8 ˜ 400 MB

Your solutions to such questions will work on your PC(not always) as it can afford this size.

But the resources at coding sites(online judges) is limited to few KBs.

Hence, the SIGABRT error and other such errors.

Conclusion:

In such questions, we ought not to declare an array or vector or any other DS of this size, but our task is to make our algorithm such efficient that it works without them(DS) or with less memory.

PS : There might be other reasons for this error; above was one of them.

You need to subscribe to the observable and pass a callback that processes emitted values

this.myService.getConfig().subscribe(val => console.log(val));

As Thrasgod correctly showed in his answer, the best way is to use the paintComponent, but also if the case is to have a semi transparent JPanel (or any other component, really) and have something not transparent inside. You have to also override the paintChildren method and set the alfa value to 1. In my case I extended the JPanel like that:

public class TransparentJPanel extends JPanel {

private float panelAlfa;
private float childrenAlfa;

public TransparentJPanel(float panelAlfa, float childrenAlfa) {
    this.panelAlfa = panelAlfa;
    this.childrenAlfa = childrenAlfa;
}

@Override
public void paintComponent(Graphics g) {
    Graphics2D g2d = (Graphics2D) g;
    g2d.setColor(getBackground());
    g2d.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.setComposite(AlphaComposite.getInstance(
            AlphaComposite.SRC_OVER, panelAlfa));
    super.paintComponent(g2d);

}

@Override
protected void paintChildren(Graphics g) {
    Graphics2D g2d = (Graphics2D) g;
    g2d.setColor(getBackground());
    g2d.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.setComposite(AlphaComposite.getInstance(
            AlphaComposite.SRC_ATOP, childrenAlfa));
  
    super.paintChildren(g); 
}
 //getter and setter
}

And in my project I only need to instantiate Jpanel jp = new TransparentJPanel(0.3f, 1.0f);, if I want only the Jpanel transparent. You could, also, mess with the JPanel shape using g2d.fillRoundRect and g2d.drawRoundRect, but it's not in the scope of this question.

Okay, this maybe an old post... but was first result in google and decided to make your own mix on this as..

FIRSTLY I WILL USE FOCUS

The reason for this is that it works nicely for the example i'm showing, if someone wants a mouse down type event then use active

THE HTML CODE:

<button class="mdT mdI1" ></button>
<button class="mdT mdI2" ></button>
<button class="mdT mdI3" ></button>
<button class="mdT mdI4" ></button>

THE CSS CODE:

/* Change Button Size/Border/BG Color And Align To Middle */
    .mdT {
        width:96px;
        height:96px;
        border:0px;
        outline:0;
        vertical-align:middle;
        background-color:#AAAAAA;
    }
    .mdT:focus {
        width:256px;
        height:256px;
    }

/* Change Images Depending On Focus */
    .mdI1       {   background-image:url('http://placehold.it/96x96/AAAAAA&text=img1');     }
    .mdI1:focus {   background-image:url('http://placehold.it/256x256/555555&text=Image+1');   }
    .mdI2       {   background-image:url('http://placehold.it/96x96/AAAAAA&text=img2');     }
    .mdI2:focus {   background-image:url('http://placehold.it/256x256/555555&text=Image+2');   }
    .mdI3       {   background-image:url('http://placehold.it/96x96/AAAAAA&text=img3');     }
    .mdI3:focus {   background-image:url('http://placehold.it/256x256/555555&text=Image+3');   }
    .mdI4       {   background-image:url('http://placehold.it/96x96/AAAAAA&text=img4');     }
    .mdI4:focus {   background-image:url('http://placehold.it/256x256/555555&text=Image+4');   }

JS FIDDLE LINK: http://jsfiddle.net/00wwkjux/

So why am i posting this in an old thread, well because the examples here vary and i thought to provide one back to the community which is a working example.

As already answered by the thread creator, they only want the effect to last during the click event. Now while this is not exact for that need, its close. active will animate while the mouse is down and any changes that you need to have last longer need to be done with javascript.

The problem is that the body of the page isn't actually visible. The DIVs under have width of 100% and have background colors themselves that override the body CSS.

To Fix the no-man's land, this might work. It's not elegant, but works.

#doc3 {
    margin: auto 10px;
    width: auto;
    height: 2000px;
    background-color: yellow;
}

In the AndroidManifest.xml, under the application tag, you can set the theme of your choice. To customize the theme, press Ctrl + Click on android:theme = "@style/AppTheme" in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

At parent= in styles.xml you can browse all available styles by using auto-complete inside the "". E.g. try parent="Theme." with your cursor right after the . and then pressing Ctrl + Space.

You can also preview themes in the preview window in Android Studio.

In the first regex, each space character is being replaced, character by character, with the empty string.

In the second regex, each contiguous string of space characters is being replaced with the empty string because of the +.

However, just like how 0 multiplied by anything else is 0, it seems as if both methods strip spaces in exactly the same way.

If you change the replacement string to '#', the difference becomes much clearer:

var str = '  A B  C   D EF ';
console.log(str.replace(/\s/g, '#'));  // ##A#B##C###D#EF#
console.log(str.replace(/\s+/g, '#')); // #A#B#C#D#EF#

I faced the same problem. Turns out I forgot to install the following package:

pip install flask_sqlalchemy

After installing the package, everything worked perfectly. Hope, it helped some other noob like me.

The <img> element is empty — it doesn't have an end tag.

If the image is a background image, use CSS. If it is a content image, then set position: relative on a container, then absolutely position the image and/or text within it.

I suppose it is better to use UTF-8 encoding in the string MD5.

public static string MD5(this string s)
{
    using (var provider = System.Security.Cryptography.MD5.Create())
    {
        StringBuilder builder = new StringBuilder();                           

        foreach (byte b in provider.ComputeHash(Encoding.UTF8.GetBytes(s)))
            builder.Append(b.ToString("x2").ToLower());

        return builder.ToString();
    }
}

Unless you're positive that the issue you're facing is indeed a bottleneck, I would go for the readable

public ArrayList filterThings() {

    ArrayList pileOfThings;
    ArrayList filteredPileOfThings = new ArrayList();

    for (Thing thingy : pileOfThings) {
        if (thingy.property != 1) {
            filteredPileOfThings.add(thingy);
        }            
    }
    return filteredPileOfThings;
}

Imagine you are designing a programming language. You decide that Strings are enclosed in quotes ("Apple"). Then you hit your first snag: how to represent quotation marks since you've already used them ? Just out of convention you decide to use \" to represent quotation marks. Then you have a second problem: how to represent \ ? Again, out of convention you decide to use \\ instead. Thankfully, the process ends there and this is sufficient. You can also use what is called an escape sequence to represent other characters such as the carriage return (\n).

For postgres, I found it easier and more accurate to use the

date_trunc

function, like:

select name, sum(count), date_trunc('minute',timestamp) as timestamp
FROM table
WHERE xxx
GROUP BY name,date_trunc('minute',timestamp)
ORDER BY timestamp

You can provide various resolutions like 'minute','hour','day' etc... to date_trunc.

I just had to uninstall HAXM and install it again. Then it started working again. Hope this helps someone!

Edit:

Oh wow, this was a long time ago. I have been using genymotion for a few months now, and never had any issues like that.

Newer versions of Python come with py, the Python Launcher, which is always in the PATH.

Here is how to invoke pip via py:

py -m pip install <packagename>

py allows having several versions of Python on the same machine.

As an example, here is how to invoke the pip from Python 2.7:

py -2.7 -m pip install <packagename>

In zsh you can use

=time ...

In bash or zsh you can use

command time ...

These (by different mechanisms) force an external command to be used.

This solution is working with Android Studio 4.0.1.

Apart from creating a new module as suggested in above solution, you can try this solution.

If you have multiple modules in your application and want to add aar to just one of the module then this solution come handy.

In your root project build.gradle

add

repositories {
mavenCentral()
flatDir {
    dirs 'libs'
}

Then in the module where you want to add the .aar file locally. simply add below lines of code.

dependencies {
api fileTree(include: ['*.aar'], dir: 'libs')
implementation files('libs/<yourAarName>.aar')

}

Happy Coding :)

Only if you open a new window using window.open() will the new window be able to close using code as I have mentioned above. This works perfectly for me :) Note : Never use href to open the page in a new tab. Window.close() does not work with "href" . Use window.open() instead.

Use the following command on your terminal (Ctrl + Alt + T):-

$ conda activate
$ anaconda-navigator

How do time zones factor in this analysis. Does a card expire in New York before California? Does it depend on the billing or shipping addresses?

You can catch that exception and return whatever you want from there.

open(target, 'a').close()
scores = {};
try:
    with open(target, "rb") as file:
        unpickler = pickle.Unpickler(file);
        scores = unpickler.load();
        if not isinstance(scores, dict):
            scores = {};

If you take a look at the following example - it uses fixed width columns, and I think this is the behavior requested.

If you use the NetBeans IDE (latest version at this time is 6.5.1), you can use it to create a basic GUI java application using File->New Project and choose the Java category then Java Desktop Application.

Once created, you will have a simple bare bones GUI app which contains an about box that can be opened using a menu selection. You should be able to adapt this to your needs and learn how to open a dialog from a button click.

You will be able to edit the dialog visually. Delete the items that are there and add some text areas. Play around with it and come back with more questions if you get stuck :)

%lld is the standard C99 way, but that doesn't work on the compiler that I'm using (mingw32-gcc v4.6.0). The way to do it on this compiler is: %I64d

So try this:

if(e%n==0)printf("%15I64d -> %1.16I64d\n",e, 4*pi);

and

scanf("%I64d", &n);

The only way I know of for doing this in a completely portable way is to use the defines in <inttypes.h>.

In your case, it would look like this:

scanf("%"SCNd64"", &n);
//...    
if(e%n==0)printf("%15"PRId64" -> %1.16"PRId64"\n",e, 4*pi);

It really is very ugly... but at least it is portable.

Not really. There are a number of dex disassembler/decompiler suites out there such as smali, or dex2jar that will generate semi-humanreadable output (in the case of dex2jar, you can get java code through the use of something like JD-GUI but the process is not perfect and it is very unlikely that you'll be able to 100% recreate your source code. However, it could potentially give you a place to start rebuilding your source tree.

You can chain .fail() callback for error response.

$.get('http://example.com/page/2/', function(data){ 
   $(data).find('#reviews .card').appendTo('#reviews');
})
.fail(function() {
  //Error logic
})

Expanding on @Robert Brisita has just expand , also if you don't want to set up all the variables of the profile in the script, you can select the variables to export on the top of the script

In crontab -e file:

In script.sh

#!/bin/bash
export JAVA_HOME=/path/to/jdk

For windows i've got same issue.

The fix was - i need to run command line as administrator.

Use position absolute. Note that this isn't how we are generally used to using position absolute which requires manually laying things out or having floating dialogs. This will automatically stretch when you resize the window or the content. I believe that this requires standards mode but will work in IE6 and above.

Just replace the div with id 'thecontent' with your content (the specified height there is just for illustration, you don't have to specify a height on the actual content.

<div style="position: relative; width: 100%;">
      <div style="position: absolute; left: 0px; right: 33%; bottom: 0px; top: 0px; background-color: blue; width: 33%;" id="navbar">nav bar</div>
      <div style="position: relative; left: 33%; width: 66%; background-color: yellow;" id="content">
         <div style="height: 10000px;" id="thecontent"></div>
      </div>
</div>

The way that this works is that the outer div acts as a reference point for the nav bar. The outer div is stretched out by the content of the 'content' div. The nav bar uses absolute positioning to stretch itself out to the height of its parent. For the horizontal alignment we make the content div offset itself by the same width of the navbar.

This is made much easier with CSS3 flex box model, but that's not available in IE yet and has some of it's own quirks.

This works on Windows with Cygwin installed:

System.getenv("NUMBER_OF_PROCESSORS")

Jin Yong - IE has an issue with polluting the global scope with object references to any DOM elements with a "name" or "id" attribute set on the "initial" page load.

Thus you may have issues due to your variable name.

Try this and see if it works.

var someOtherName="abc";
//  ^^^^^^^^^^^^^
document.getElementById('msg').value = someOtherName;
document.getElementById('sp_100').checked = true;

There is a chance (in your original code) that IE attempts to set the value of the input to a reference to that actual element (ignores the error) but leaves you with no new value.

Keep in mind that in IE6/IE7 case doesn't matter for naming objects. IE believes that "foo" "Foo" and "FOO" are all the same object.

I downloaded this "IE Tab Multi" from Chrome. It works good! http://iblogbox.com/chrome/ietab/alert.php

Depends on what they looked like. I use gitx which makes pictures like this one:

You can compare git log --graph vs. gitk on a 24-way octopus merge (originally from http://clojure-log.n01se.net/date/2008-12-24.html):

I guess you need to add a reference to the System.Configuration assembly if that have not already been added.

Also, you may need to insert the following line at the top of your code file:

using System.Configuration;

To answer your questions there are simply two steps:-

1. Pull the latest changes from your git repo using git pull
2. Clean your local working directory having unstaged changes using git checkout -- . .This will show the latest changes in your local repo from your remote git repo. cleaning all the local unstaged changes.

Please note git checkout -- . will discard all your changes in the local working directory. In case you want to discard any change for selective file use git checkout -- <filename>. And in case you don't want to lose your unstaged changes use git stash as it will clean your local working directory of all the unstaged changes while saving it if you need it in the future.

To return a value from a VBScript function, assign the value to the name of the function, like this:

Function getNumber
    getNumber = "423"
End Function

Here is a short code snippet for shadowing cin/cout useful for programming contests:

#include <bits/stdc++.h>

using namespace std;

int main() {
    ifstream cin("input.txt");
    ofstream cout("output.txt");

    int a, b;   
    cin >> a >> b;
    cout << a + b << endl;
}

This gives additional benefit that plain fstreams are faster than synced stdio streams. But this works only for the scope of single function.

Global cin/cout redirect can be written as:

#include <bits/stdc++.h>

using namespace std;

void func() {
    int a, b;
    std::cin >> a >> b;
    std::cout << a + b << endl;
}

int main() {
    ifstream cin("input.txt");
    ofstream cout("output.txt");

    // optional performance optimizations    
    ios_base::sync_with_stdio(false);
    std::cin.tie(0);

    std::cin.rdbuf(cin.rdbuf());
    std::cout.rdbuf(cout.rdbuf());

    func();
}

Note that ios_base::sync_with_stdio also resets std::cin.rdbuf. So the order matters.

See also Significance of ios_base::sync_with_stdio(false); cin.tie(NULL);

Std io streams can also be easily shadowed for the scope of single file, which is useful for competitive programming:

#include <bits/stdc++.h>

using std::endl;

std::ifstream cin("input.txt");
std::ofstream cout("output.txt");

int a, b;

void read() {
    cin >> a >> b;
}

void write() {
    cout << a + b << endl;
}

int main() {
    read();
    write();
}

But in this case we have to pick std declarations one by one and avoid using namespace std; as it would give ambiguity error:

error: reference to 'cin' is ambiguous
     cin >> a >> b;
     ^
note: candidates are: 
std::ifstream cin
    ifstream cin("input.txt");
             ^
    In file test.cpp
std::istream std::cin
    extern istream cin;  /// Linked to standard input
                   ^

If you are using AdonisJS and have mixed IDs such as ABC-202, ABC-201..., you can combine raw queries with Query Builder and implement the solution above (https://stackoverflow.com/a/25061144/4040835) as follows:

const sortField =
  'membership_id'
const sortDirection =
  'asc'
const subquery = UserProfile.query()
  .select(
    'user_profiles.id',
    'user_profiles.user_id',
    'user_profiles.membership_id',
    'user_profiles.first_name',
    'user_profiles.middle_name',
    'user_profiles.last_name',
    'user_profiles.mobile_number',
    'countries.citizenship',
    'states.name as state_of_origin',
    'user_profiles.gender',
    'user_profiles.created_at',
    'user_profiles.updated_at'
  )
  .leftJoin(
    'users',
    'user_profiles.user_id',
    'users.id'
  )
  .leftJoin(
    'countries',
    'user_profiles.nationality',
    'countries.id'
  )
  .leftJoin(
    'states',
    'user_profiles.state_of_origin',
    'states.id'
  )
  .orderByRaw(
    `SUBSTRING(:sortField:,3,15)*1 ${sortDirection}`,
    {
      sortField: sortField,
    }
  )
  .paginate(
    page,
    per_page
  )

NOTES: In this line: SUBSTRING(:sortField:,3,15)*1 ${sortDirection},

1. '3' stands for the index number of the last non-numerical character before the digits. If your mixed ID is "ABC-123," your index number will be 4.
2. '15' is used to catch as any number of digits as possible after the hyphen.
3. '1' performs a mathematical operation on the substring which effectively casts the substring to a number.

Yes, it is recommended to put the GA code in the footer anyway, as the page shouldnt count as a page visit until its read all the markup.

To find any file location

1. In windows start menu Search box
2. type in svcutil.exe
3. Wait for results to populate
4. Right click on svcutil.exe and Select 'Open file location'
5. Copy Windows explorer path

To expand on the answer provided by @Orion Edwards, this is how you would do fully from code-behind (no styles set). Basically create a custom class that inherits from Border which has its Child set to a TextBox. The example below assumes that you only want a single line and that the border is a child of a Canvas. Also assumes you would need to adjust the MaxLength property of the TextBox based on the width of the Border. The example below also sets the cursor of the Border to mimic a Textbox by setting it to the type 'IBeam'. A margin of '3' is set so that the TextBox isn't absolutely aligned to the left of the border.

double __dX = 20;
double __dY = 180;
double __dW = 500;
double __dH = 40;
int __iMaxLen = 100;

this.m_Z3r0_TextBox_Description = new CZ3r0_TextBox(__dX, __dY, __dW, __dH, __iMaxLen, TextAlignment.Left);
this.Children.Add(this.m_Z3r0_TextBox_Description);

when I am testing "typeof obj === undefined", the alert(typeof obj) returning object, even though obj is undefined. Since obj is type of Object its returning Object, not undefined.

So after hours of testing I opted below technique.

if(document.getElementById(obj) !== null){
//do...
}else{
//do...
}

I am not sure why the first technique didn't work.But I get done my work using this.

You can use pure Python to do it:

import json
list = [1, 2, (3, 4)] # Note that the 3rd element is a tuple (3, 4)
json.dumps(list) # '[1, 2, [3, 4]]'

Edittext cursor color you want changes your color.
   <EditText  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:textCursorDrawable="@drawable/color_cursor"
    />

Then create drawalble xml: color_cursor

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <size android:width="3dp" />
    <solid android:color="#FFFFFF"  />
</shape>

Python

element.get_attribute("attribute name")

Java

element.getAttribute("attribute name")

Ruby

element.attribute("attribute name")

C#

element.GetAttribute("attribute name");

This should do it:

[^a-zA-Z\d\s:]

time1 is the key of the most outer dictionary, eg, feb2012. So then you're trying to index the string, but you can only do this with integers. I think what you wanted was:

for info in courses[time1][course]:

As you're going through each dictionary, you must add another nest.

Try this for IE11

<iframe name="Stack" src="http://stackoverflow.com/" style='height: 100%; width: 100%;' frameborder="0" scrolling="no" id="iframe">...</iframe>

You may need to go to Window -> Android SDK Manager -> Packages -> Reload to fetch latest updates and then update the SDK.

<xsl:if test="not contains(hhref,'1234')">

Add two headers Content-Type and Accept to be equal to application/json.

handleGetJson(){
  console.log("inside handleGetJson");
  fetch(`./fr.json`, {
      headers : { 
        'Content-Type': 'application/json',
        'Accept': 'application/json'
       }

    })
    .then((response) => response.json())
    .then((messages) => {console.log("messages");});
}

if it is a RSA key

openssl rsa  -pubout -in my_rsa_key.pem

if you need it in a format for openssh , please see Use RSA private key to generate public key?

Note that public key is generated from the private key and ssh uses the identity file (private key file) to generate and send public key to server and un-encrypt the encrypted token from the server via the private key in identity file.

The rvest along with xml2 is another popular package for parsing html web pages.

library(rvest)
theurl <- "http://en.wikipedia.org/wiki/Brazil_national_football_team"
file<-read_html(theurl)
tables<-html_nodes(file, "table")
table1 <- html_table(tables[4], fill = TRUE)

The syntax is easier to use than the xml package and for most web pages the package provides all of the options ones needs.

First of all, do you really need to store indices like this? Have you looked into std::map, enabling you to store key => value pairs?

Secondly, if you used iterators instead, you would be able to return std::vector.end() to indicate an invalid result. To convert an iterator to an index you simply use

size_t i = it - myvector.begin();

What is the reason to use the strings as file names? If human readability is not a factor I would go with base64 module which can produce file system safe strings. It won't be readable but you won't have to deal with collisions and it is reversible.

import base64
file_name_string = base64.urlsafe_b64encode(your_string)

Update: Changed based on Matthew comment.

Sometimes you have to do something funky. Let's say you want to read from a command (the date example by SDGuero for example) but you want to avoid multiple forks.

read month day year << DATE_COMMAND
 $(date "+%m %d %Y")
DATE_COMMAND
echo $month $day $year

You could also pipe into the read command, but then you'd have to use the variables within a subshell:

day=n/a; month=n/a; year=n/a
date "+%d %m %Y" | { read day month year ; echo $day $month $year; }
echo $day $month $year

results in...

13 08 2013
n/a n/a n/a

Well, the above answer is correct, auto_now_add and auto_now would do it, but it would be better to make an abstract class and use it in any model where you require created_at and updated_at fields.

class TimeStampMixin(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        abstract = True

Now anywhere you want to use it you can do a simple inherit and you can use timestamp in any model you make like.

class Posts(TimeStampMixin):
    name = models.CharField(max_length=50)
    ...
    ...

In this way, you can leverage object-oriented reusability, in Django DRY(don't repeat yourself)

Seems like you could use date() and the lowercase "L" format character in the following way:

$weekday_name = date("l", $timestamp);

Works well for me, here is the doc: http://php.net/manual/en/function.date.php

I fixed it, I'm not exactly sure what I did. I tried simply pushing and pulling using:

git pull <remote> dev instead of git pull <remote> master:dev

I met the same problem. I found the solution in the solution from kb.vmware.com.
It works for me by adding

usb.quirks.device0 = "0xvid:0xpid skip-refresh"

Detail as below:

1. Shut down the virtual machine and quit Workstation/Fusion.
   
   Caution: Do not skip this step.
    
2. Open the vmware.log file within the virtual machine bundle. For more information, see Locating a virtual machine bundle in VMware Workstation/Fusion (1007599).
3. In the Filter box at the top of the Console window, enter the name of the device manufacturer.
   
   For example, if you enter the name Apple, you see a line that looks similar to:
   
   

   vmx | USB: Found device [name:Apple\ IR\ Receiver vid:05ac pid:8240 path:13/7/2 speed:full family:hid]

   
   
   The line has the name of the USB device and its vid and pid information. Make a note of the vid and pid values.
    

4. Open the .vmx file using a text editor. For more information, see Editing the .vmx file for your Workstation/Fusion virtual machine (1014782).
5. Add this line to the .vmx file, replacing vid and pid with the values noted in Step 2, each prefixed by the number 0 and the letter x .
   
   

   usb.quirks.device0 = "0xvid:0xpid skip-reset"
   
   

   For example, for the Apple device found in step 2, this line is:
   
   

   usb.quirks.device0 = "0x05ac:0x8240 skip-reset"
    

6. Save the .vmx file.
7. Re-open Workstation/Fusion. The edited .vmx file is reloaded with the changes.
8. Start the virtual machine, and connect the device.
9. If the issue is not resolved, replace the quirks line added in Step 4 with one of these lines, in the order provided, and repeat Steps 5 to 8:

usb.quirks.device0 = "0xvid:0xpid skip-refresh"
usb.quirks.device0 = "0xvid:0xpid skip-setconfig"
usb.quirks.device0 = "0xvid:0xpid skip-reset, skip-refresh, skip-setconfig"

Notes:

• Use one of these lines at a time. If one does not work, replace it with another one in the list. Do not add more than one of these in the .vmx file at a time.
• The last line uses all three quirks in combination. Use this only if the other three lines do not work.

Refer this to see in detail.

The iOS 8.0 simulator runtime has a bug whereby if your network configuration changes while the simulated device is booted, higher level APIs (eg: CFNetwork) in the simulated runtime will think that it has lost network connectivity. Currently, the advised workaround is to simply reboot the simulated device when your network configuration changes.

If you are impacted by this issue, please file additional duplicate radars at http://bugreport.apple.com to get it increased priority.

If you see this issue without having changed network configurations, then that is not a known bug, and you should definitely file a radar, indicating that the issue is not the known network-configuration-changed bug.

Yet another way is to read the composer.json file, but it can end with wildcard character *

I think what you are looking for is

  background-repeat: no-repeat;
  background-position: center;

  -moz-background-size: contain;
  -o-background-size: contain;
  background-size: contain;
}

pluck(column_name)

This method is designed to perform select by a single column as direct SQL query Returns Array with values of the specified column name The values has same data type as column.

Examples:

Person.pluck(:id) # SELECT people.id FROM people
Person.uniq.pluck(:role) # SELECT DISTINCT role FROM people
Person.where(:confirmed => true).limit(5).pluck(:id)

see http://api.rubyonrails.org/classes/ActiveRecord/Calculations.html#method-i-pluck

Its introduced rails 3.2 onwards and accepts only single column. In rails 4, it accepts multiple columns

The following example demonstrates how to do this:

DateTime a = new DateTime(2010, 05, 12, 13, 15, 00);
DateTime b = new DateTime(2010, 05, 12, 13, 45, 00);
Console.WriteLine(b.Subtract(a).TotalMinutes);

When executed this prints "30" since there is a 30 minute difference between the date/times.

The result of DateTime.Subtract(DateTime x) is a TimeSpan Object which gives other useful properties.

Look at DATEADD

SELECT DATEADD(mm, 1, OrderDate)AS TimeFrame

Here's the MSDN

In your case

...WHERE reference_dt = DATEADD(MM,1, myColDate)

Plenty of good solutions exist for finding all the prime factors of not too large numbers. I just wanted to point out, that once you have them, no computation is required to get all the factors.

if N = p_1^{a}*p_{2}^{b}*p_{3}^{c}.....

Then the number of factors is clearly (a+1)(b+1)(c+1).... since every factor can occur zero up to a times.

e.g. 12 = 2^2*3^1 so it has 3*2 = 6 factors. 1,2,3,4,6,12

======

I originally thought that you just wanted the number of distinct factors. But the same logic applies. You just iterate over the set of numbers corresponding to the possible combinations of exponents.

so int he example above:

00
01
10
11
20
21

gives you the 6 factors.

If you are sure you want to remove all commit history, simply delete the .git directory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:

git init
git remote add origin [email protected]:user/repo

now commit your current version of code

git add *
git commit -am 'message'

and finally force the update to GitHub:

git push -f origin master

However, I suggest backing up the history (the .git folder in the repository) before taking these steps!

In Kotlin it would be

private fun setupToolbar(){
    toolbar.title = getString(R.string.YOUR_TITLE)
    setSupportActionBar(toolbar)
    supportActionBar?.setDisplayHomeAsUpEnabled(true)
    supportActionBar?.setDisplayShowHomeEnabled(true)
}

// don't forget click listener for back button
override fun onSupportNavigateUp(): Boolean {
    onBackPressed()
    return true
}

If you are using Java 8

char[] charArray = IntStream.rangeClosed('A', 'Z')
    .mapToObj(c -> "" + (char) c).collect(Collectors.joining()).toCharArray();

LAZY: It fetches the child entities lazily i.e at the time of fetching parent entity it just fetches proxy(created by cglib or any other utility) of the child entities and when you access any property of child entity then it is actually fetched by hibernate.

EAGER: it fetches the child entities along with parent.

For better understanding go to Jboss documentation or you can use hibernate.show_sql=true for your app and check the queries issued by the hibernate.

1) Go to Phone Setting > Developer options > Revoke USB debugging.

2) Turn off USB debugging and Restart Again.

It will work definitely, in my case it worked.

Alternatively you can do like this:

var result = list1.Where(p => list2.All(x => x.Id != p.Id));

Insted of

drawer.setDrawerListener(toggle);

You can use

drawer.addDrawerListener(toggle);

It's not only a Python bug with * actually, it can also happen when you pass a string as a part of your regular expression to be compiled, like ;

import re
input_line = "string from any input source"
processed_line= "text to be edited with {}".format(input_line)
target = "text to be searched"
re.search(processed_line, target)

this will cause an error if processed line contained some "(+)" for example, like you can find in chemical formulae, or such chains of characters. the solution is to escape but when you do it on the fly, it can happen that you fail to do it properly...

First of all we open the file and as datafile then we apply .read() method reads the file contents and then we split the data which returns something like: ['5', '10', '6', '6', '20', '1', '7', '30', '4', '8', '40', '3', '9', '23', '1', '4', '13', '6'] and the we applied list slicing on this list to start from the element at index position 1 and skip next 3 elements untill it hits the end of the loop.

with open("sample.txt", "r") as datafile:
    print datafile.read().split()[1::3]

Output:

['10', '20', '30', '40', '23', '13']

try this one out resizeable button

<button type="submit me" style="height: 25px; width: 100px">submit me</button>

This can be achived by specifying port via the -P switch:

String user_email = email.getText().toString().trim();

    .createUserWithEmailAndPassword(user_email,user_password)

I hope it helps, regards!

make these changes in your div's style

1. z-index:100; some higher value makes sure that this element is above all
2. position:fixed; this makes sure that even if scrolling is done,

div lies on top and always visible

The performance of the suggested answer is fine. According to the MongoDB documentation:

When a $sort immediately precedes a $limit, the optimizer can coalesce the $limit into the $sort. This allows the sort operation to only maintain the top n results as it progresses, where n is the specified limit, and MongoDB only needs to store n items in memory.

Changed in version 4.0.

So in the case of

db.collection.find().sort({age:-1}).limit(1)

we get only the highest element WITHOUT sorting the collection because of the mentioned optimization.

Dynamic programming is a technique used to avoid computing multiple times the same subproblem in a recursive algorithm.

Let's take the simple example of the Fibonacci numbers: finding the n ^th Fibonacci number defined by

F_n = F_n-1 + F_n-2 and F₀ = 0, F₁ = 1

Recursion

The obvious way to do this is recursive:

def fibonacci(n):
    if n == 0:
        return 0
    if n == 1:
        return 1

    return fibonacci(n - 1) + fibonacci(n - 2)

Dynamic Programming

• Top Down - Memoization

The recursion does a lot of unnecessary calculations because a given Fibonacci number will be calculated multiple times. An easy way to improve this is to cache the results:

cache = {}

def fibonacci(n):
    if n == 0:
        return 0
    if n == 1:
        return 1
    if n in cache:
        return cache[n]

    cache[n] = fibonacci(n - 1) + fibonacci(n - 2)

    return cache[n]

• Bottom-Up

A better way to do this is to get rid of the recursion all-together by evaluating the results in the right order:

cache = {}

def fibonacci(n):
    cache[0] = 0
    cache[1] = 1

    for i in range(2, n + 1):
        cache[i] = cache[i - 1] +  cache[i - 2]

    return cache[n]

We can even use constant space and store only the necessary partial results along the way:

def fibonacci(n):
  fi_minus_2 = 0
  fi_minus_1 = 1

  for i in range(2, n + 1):
      fi = fi_minus_1 + fi_minus_2
      fi_minus_1, fi_minus_2 = fi, fi_minus_1

  return fi

• How apply dynamic programming?

  1. Find the recursion in the problem.
  2. Top-down: store the answer for each subproblem in a table to avoid having to recompute them.
  3. Bottom-up: Find the right order to evaluate the results so that partial results are available when needed.

Dynamic programming generally works for problems that have an inherent left to right order such as strings, trees or integer sequences. If the naive recursive algorithm does not compute the same subproblem multiple times, dynamic programming won't help.

I made a collection of problems to help understand the logic: https://github.com/tristanguigue/dynamic-programing

Mostly recursion is very natural for dealing with recursive data structures. This basically means list structures, and tree structures. But recursion is also a nice natural way of /creating/ tree structures on the fly in some way, by divide-and-conquer for instance quicksort, or binary search.

I think your question is a bit misguided in one sense. What's not real-world about depth first search? There's a lot you can do with depth-first search.

For instance, another example I thought of giving is recursive descent compilation. It is enough of a real-world problem to have been used in many real-world compilers. But you could argue it is DFS, it is basically a depth-first-search for a valid parse tree.

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

try/catch is scripted syntax. So any time you are using declarative syntax to use something from scripted in general you can do so by enclosing the scripted syntax in the scripts block in a declarative pipeline. So your try/catch should go inside stage >steps >script.

This holds true for any other scripted pipeline syntax you would like to use in a declarative pipeline as well.

Spaces are simply replaced by "%20" like :

http://www.example.com/my%20beautiful%20page

you can use index and columns attributes of pandas.DataFrame. NOTE: number of elements of list must match the number of rows/columns.

#       A   B   C
# ONE   11  12  13
# TWO   21  22  23
# THREE 31  32  33

df.index = [1, 2, 3]
df.columns = ['a', 'b', 'c']
print(df)

#     a   b   c
# 1  11  12  13
# 2  21  22  23
# 3  31  32  33

Also make sure that you don't declare it an array and then try to assign something else to the array like a string, float, integer. I had that problem. If you do some echos of output I was seeing what I wanted the first time, but not after another pass of the same code.

Update with Angular 7.x.x, encounter the same issue in one of my modules.

If it lies in your independent module, add these extra modules:

import { CommonModule } from "@angular/common";
import { FormsModule } from "@angular/forms";

@NgModule({
  imports: [CommonModule, FormsModule], // the order can be random now;
  ...
})

If it lies in your app.module.ts, add these modules:

import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';

@NgModule({
  imports:      [ FormsModule, BrowserModule ], // order can be random now
  ...
})

A simple demo to prove the case.

Maybe I am missing something (lots of many-upvotes-members answers here that seem to be looking at this different to I, which would seem implausible that I am correct), but length is not the correct terminology for counting something. Length is usually used to obtain what you are getting, and not what you are wanting.

$cars.count should give you what you seem to be looking for.

Make sure you've set your locale settings right before running the script from the shell, e.g.

$ locale -a | grep "^en_.\+UTF-8"
en_GB.UTF-8
en_US.UTF-8
$ export LC_ALL=en_GB.UTF-8
$ export LANG=en_GB.UTF-8

Docs: man locale, man setlocale.

You can use any commonly available hash algorithm (eg. SHA-1), which will give you a slightly longer result than what you need. Simply truncate the result to the desired length, which may be good enough.

For example, in Python:

>>> import hashlib
>>> hash = hashlib.sha1("my message".encode("UTF-8")).hexdigest()
>>> hash
'104ab42f1193c336aa2cf08a2c946d5c6fd0fcdb'
>>> hash[:10]
'104ab42f11'

One last thing is to check for Event Listeners > "scroll" and test deleting them.

Even if you delete the Javascript that created them, the listeners will stick around and prevent scrolling.

Here you have two simple functions of UIImage extension:

func scaledWithMaxWidthOrHeightValue(value: CGFloat) -> UIImage? {

    let width = self.size.width
    let height = self.size.height

    let ratio = width/height

    var newWidth = value
    var newHeight = value

    if ratio > 1 {
        newWidth = width * (newHeight/height)
    } else {
        newHeight = height * (newWidth/width)
    }

    UIGraphicsBeginImageContextWithOptions(CGSize(width: newWidth, height: newHeight), false, 0)

    draw(in: CGRect(x: 0, y: 0, width: newWidth, height: newHeight))

    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return image
}

func scaled(withScale scale: CGFloat) -> UIImage? {

    let size = CGSize(width: self.size.width * scale, height: self.size.height * scale)

    UIGraphicsBeginImageContextWithOptions(size, false, 0)

    draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height))

    let image = UIGraphicsGetImageFromCurrentImageContext()

    UIGraphicsEndImageContext()

    return image
}

Generally it means that you are providing an index for which a list element does not exist.

E.g, if your list was [1, 3, 5, 7], and you asked for the element at index 10, you would be well out of bounds and receive an error, as only elements 0 through 3 exist.

What's even cooler is the fact that you can use an inline Table-Valued Function to select which (and how many via TOP) row(s) to update. That is:

UPDATE MyTable
SET Column1=@Value1
FROM tvfSelectLatestRowOfMyTableMatchingCriteria(@Param1,@Param2,@Param3)

For the table valued function you have something interesting to select the row to update like:

CREATE FUNCTION tvfSelectLatestRowOfMyTableMatchingCriteria
(
    @Param1 INT,
    @Param2 INT,
    @Param3 INT
)
RETURNS TABLE AS RETURN
(
    SELECT TOP(1) MyTable.*
    FROM MyTable
    JOIN MyOtherTable
      ON ...
    JOIN WhoKnowsWhatElse
      ON ...
    WHERE MyTable.SomeColumn=@Param1 AND ...
    ORDER BY MyTable.SomeDate DESC
)

..., and there lies (in my humble opinion) the true power of updating only top selected rows deterministically while at the same time simplifying the syntax of the UPDATE statement.

1) use for tommorow's date startDate: '+1d'

2) use for yesterday's date startDate: '-1d'

3) use for today's date startDate: new Date()

I realize this is an old question and referring to TOAD but if you need to code around this using c# you can split up the list through a for loop. You can essentially do the same with Java using subList();

    List<Address> allAddresses = GetAllAddresses();
    List<Employee> employees = GetAllEmployees(); // count > 1000

    List<Address> addresses = new List<Address>();

    for (int i = 0; i < employees.Count; i += 1000)
    {
        int count = ((employees.Count - i) < 1000) ? (employees.Count - i) - 1 : 1000;
        var query = (from address in allAddresses
                     where employees.GetRange(i, count).Contains(address.EmployeeId)
                     && address.State == "UT"
                     select address).ToList();

        addresses.AddRange(query);
    }

Hope this helps someone.

According to this article on sqlserverstudymaterial;

Remember that "%Privileged time" is not based on 100%.It is based on number of processors.If you see 200 for sqlserver.exe and the system has 8 CPU then CPU consumed by sqlserver.exe is 200 out of 800 (only 25%).

If "% Privileged Time" value is more than 30% then it's generally caused by faulty drivers or anti-virus software. In such situations make sure the BIOS and filter drives are up to date and then try disabling the anti-virus software temporarily to see the change.

If "% User Time" is high then there is something consuming of SQL Server. There are several known patterns which can be caused high CPU for processes running in SQL Server including

simplifying the general answer

SQL Case Sensitive String Compare

These examples may be helpful:

Declare @S1 varchar(20) = 'SQL'
Declare @S2 varchar(20) = 'sql'

  
if @S1 = @S2 print 'equal!' else print 'NOT equal!' -- equal (default non-case sensitivity for SQL

if cast(@S1 as binary) = cast(Upper(@S2) as binary) print 'equal!' else print 'NOT equal!' -- equal

if cast(@S1 as binary) = cast(@S2 as binary) print 'equal!' else print 'NOT equal!' -- not equal

if  @S1 COLLATE Latin1_General_CS_AS  = Upper(@S2) COLLATE Latin1_General_CS_AS  print 'equal!' else print 'NOT equal!' -- equal

if  @S1 COLLATE Latin1_General_CS_AS  = @S2 COLLATE Latin1_General_CS_AS  print 'equal!' else print 'NOT equal!' -- not equal

 

The convert is probably more efficient than something like runtime calculation of hashbytes, and I'd expect the collate may be even faster.

You need to set the timeout to "None" when you open the serial port:

ser = serial.Serial(**bco_port**, timeout=None, baudrate=115000, xonxoff=False, rtscts=False, dsrdtr=False) 

This is a blocking command, so you are waiting until you receive data that has newline (\n or \r\n) at the end: line = ser.readline()

Once you have the data, it will return ASAP.

You can use std::to_string available in C++11 as suggested by Matthieu M.:

std::to_string(42);

Or, if performance is critical (for example, if you do lots of conversions), you can use fmt::format_int from the {fmt} library to convert an integer to std::string:

fmt::format_int(42).str();

Or a C string:

fmt::format_int f(42);
f.c_str();

The latter doesn't do any dynamic memory allocations and is more than 70% faster than std::to_string on Boost Karma benchmarks. See Converting a hundred million integers to strings per second for more details.

Note that both are thread-safe.

Unlike std::to_string, fmt::format_int doesn't require C++11 and works with any C++ compiler.

Disclaimer: I'm the author of the {fmt} library.

Does "pure HTML/CSS" exclude the use of tables? Because they will easily do what you want:

<table>
    <tr>
        <td valign="top"><img src="myImage.jpg" alt="" /></td>
        <td valign="middle">This is my text!</td>
    </tr>
</table>

Flame me all you like, but that works (and works in old, janky browsers).

Say you let vmware use port 443, and use another ssl port in XAMPP Apache (httpd-ssl.conf) :

The red error will keep popping in XAMPP Control Panel. You also need to change the port in the XAMPP Control Panel configuration :

In XAMPP Control Panel, click the "Config" button (top-left). Then click "Service and Port Settings". There you can set the ports to match the ports used by Apache.

The problem with shelling out to a batch file or EXE is that a service may or may not have the permissions required to run the external app.

The cleanest way to do this that I have found is to use the OnStop() method, which is the entry point for the Service Control Manager. Then all your cleanup code will run, and you won't have any hanging sockets or other processes, assuming your stop code is doing its job.

To do this you need to set a flag before you terminate that tells the OnStop method to exit with an error code; then the SCM knows that the service needs to be restarted. Without this flag you won't be able to stop the service manually from the SCM. This also assumes you have set up the service to restart on an error.

Here's my stop code:

...

bool ABORT;

protected override void OnStop()
{
    Logger.log("Stopping service");
    WorkThreadRun = false;
    WorkThread.Join();
    Logger.stop();
    // if there was a problem, set an exit error code
    // so the service manager will restart this
    if(ABORT)Environment.Exit(1);
}

If the service runs into a problem and needs to restart, I launch a thread that stops the service from the SCM. This allows the service to clean up after itself:

...

if(NeedToRestart)
{
    ABORT = true;
    new Thread(RestartThread).Start();
}

void RestartThread()
{
    ServiceController sc = new ServiceController(ServiceName);
    try
    {
        sc.Stop();
    }
    catch (Exception) { }
}

In order to count the number of keywords in a dictionary:

def dict_finder(dict_finders):
    x=input("Enter the thing you want to find: ")
    if x in dict_finders:
        print("Element found")
    else:
        print("Nothing found:")

You can use "ImageBackground" component on React Native.

<ImageBackground
  source={yourSourceFile}
  style={{width: '100%', height: '100%'}}
> 
    <....yourContent...>
</ImageBackground>

As others have answered, there is no current way to add maxlength directly to a CSS class.

However, this creative solution can achieve what you are looking for.

I have the jQuery in a file named maxLengths.js which I reference in site (site.master for ASP)

run the snippet to see it in action, works well.

jquery, css, html:

$(function () {_x000D_
    $(".maxLenAddress1").keypress(function (event) {_x000D_
_x000D_
        if ($(this).val().length == 5) { /* obv 5 is too small for an address field, just want to use as an example though */_x000D_
            return false;_x000D_
        } else {_x000D_
            return true;_x000D_
        }_x000D_
_x000D_
    });_x000D_
});

.maxLenAddress1{} /* this is here mostly for intellisense usage, but can be altered if you like */

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
_x000D_
<input type="text" class="maxLenAddress1" />

The advantage of using this: if it is decided the max length for this type of field needs to be pushed out or in across your entire application you can change it in one spot. Comes in handy for field lengths for things like customer codes, full name fields, email fields, any field common across your application.

Adding to @MK Yung and @Bruno's answer.. Do enter a password for the destination keystore. I saw my console hanging when I entered the command without a password.

That's the platform toolset for VS2015. You uninstalled it, therefore it is no longer available.

To change your Platform Toolset:

1. Right click your project, go to Properties.
2. Under Configuration Properties, go to General.
3. Change your Platform Toolset to one of the available ones.

You can use as below

$('#showFrame').on("load", function () {
        loader.hide();
});

Enter

git log .

from the specific directory, it also gives commits in that directory.

You could put it all in one function:

function sum( obj ) {_x000D_
  var sum = 0;_x000D_
  for( var el in obj ) {_x000D_
    if( obj.hasOwnProperty( el ) ) {_x000D_
      sum += parseFloat( obj[el] );_x000D_
    }_x000D_
  }_x000D_
  return sum;_x000D_
}_x000D_
    _x000D_
var sample = { a: 1 , b: 2 , c:3 };_x000D_
var summed = sum( sample );_x000D_
console.log( "sum: "+summed );

function sum(obj) {_x000D_
  return Object.keys(obj).reduce((sum,key)=>sum+parseFloat(obj[key]||0),0);_x000D_
}_x000D_
let sample = { a: 1 , b: 2 , c:3 };_x000D_
_x000D_
console.log(`sum:${sum(sample)}`);

But this seems to be way slower: jsperf.com

You should use either indexing or the subset function. For example :

R> df <- data.frame(x=1:5, y=2:6, z=3:7, u=4:8)
R> df
  x y z u
1 1 2 3 4
2 2 3 4 5
3 3 4 5 6
4 4 5 6 7
5 5 6 7 8

Then you can use the which function and the - operator in column indexation :

R> df[ , -which(names(df) %in% c("z","u"))]
  x y
1 1 2
2 2 3
3 3 4
4 4 5
5 5 6

Or, much simpler, use the select argument of the subset function : you can then use the - operator directly on a vector of column names, and you can even omit the quotes around the names !

R> subset(df, select=-c(z,u))
  x y
1 1 2
2 2 3
3 3 4
4 4 5
5 5 6

Note that you can also select the columns you want instead of dropping the others :

R> df[ , c("x","y")]
  x y
1 1 2
2 2 3
3 3 4
4 4 5
5 5 6

R> subset(df, select=c(x,y))
  x y
1 1 2
2 2 3
3 3 4
4 4 5
5 5 6

I needed similar for SQL SERVER 2000 and, as @Mitch points out, this only works inm 2005+.

Should it help anyone else, this is what worked for me in the end:

if exists (
    select * 
    from 
        sysobjects, syscolumns 
    where 
        sysobjects.id = syscolumns.id 
        and sysobjects.name = 'table' 
        and syscolumns.name = 'column')

You're looking for this on the command line (for a class called MyClass):

On Unix/Linux:

javap -verbose MyClass | grep "major"

On Windows:

javap -verbose MyClass | findstr "major"

You want the major version from the results. Here are some example values:

• Java 1.2 uses major version 46
• Java 1.3 uses major version 47
• Java 1.4 uses major version 48
• Java 5 uses major version 49
• Java 6 uses major version 50
• Java 7 uses major version 51
• Java 8 uses major version 52
• Java 9 uses major version 53
• Java 10 uses major version 54
• Java 11 uses major version 55

Javascript always passes by value. However, if you pass an object to a function, the "value" is really a reference to that object, so the function can modify that object's properties but not cause the variable outside the function to point to some other object.

An example:

function changeParam(x, y, z) {
  x = 3;
  y = "new string";
  z["key2"] = "new";
  z["key3"] = "newer";

  z = {"new" : "object"};
}

var a = 1,
    b = "something",
    c = {"key1" : "whatever", "key2" : "original value"};

changeParam(a, b, c);

// at this point a is still 1
// b is still "something"
// c still points to the same object but its properties have been updated
// so it is now {"key1" : "whatever", "key2" : "new", "key3" : "newer"}
// c definitely doesn't point to the new object created as the last line
// of the function with z = ...

It changes in angular 2.1.0

/* And this to your table's `td` elements. */
#page td {
   padding: 0;

From Goetz - Java Concurrency in Practice:

6. Debugging tip: For server applications, be sure to always specify the -server JVM command line switch when invoking the JVM, even for development and testing. The server JVM performs more optimization than the client JVM, such as hoisting variables out of a loop that are not modified in the loop; code that might appear to work in the development environment (client JVM) can break in the deployment environment (server JVM). For example, had we “forgotten” to declare the variable asleep as volatile in Listing 3.4, the server JVM could hoist the test out of the loop (turning it into an infinite loop), but the client JVM would not. An infinite loop that shows up in development is far less costly than one that only shows up in production.

Listing 3.4. Counting sheep.

volatile boolean asleep; ... while (!asleep) countSomeSheep();

I happened to encounter this similar SSL problem a few days ago. The problem is your npm does not set root certificate for the certificate used by https://registry.npmjs.org.

Solutions:

1. Use wget https://registry.npmjs.org/coffee-script --ca-certificate=./DigiCertHighAssuranceEVRootCA.crt to fix wget problem
2. Use npm config set cafile /path/to/DigiCertHighAssuranceEVRootCA.crt to set root certificate for your npm program.

you can download root certificate from : https://www.digicert.com/CACerts/DigiCertHighAssuranceEVRootCA.crt

Notice: Different program may use different way of managing root certificate, so do not mix browser's with others.

Analysis:

let's fix your wget https://registry.npmjs.org/coffee-script problem first. your snippet says:

        ERROR: cannot verify registry.npmjs.org's certificate,
        issued by /C=US/ST=CA/L=Oakland/O=npm/OU=npm 
       Certificate Authority/CN=npmCA/[email protected]:
       Unable to locally verify the issuer's authority.

This means that your wget program cannot verify https://registry.npmjs.org's certificate. There are two reasons that may cause this problem:

1. Your wget program does not have this domain's root certificate. The root certificate usually ship with system.
2. The domain does not pack root certificate into his certificate.

So the solution is explicitly set root certificate for https://registry.npmjs.org. We can use openssl to make sure that the reason bellow is the problem.

Try openssl s_client -host registry.npmjs.org -port 443 on the command line and we will get this message (first several lines):

    CONNECTED(00000003)
    depth=1 /C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance CA-3
    verify error:num=20:unable to get local issuer certificate
    verify return:0

    Certificate chain
     0 s:/C=US/ST=California/L=San Francisco/O=Fastly, Inc./CN=a.sni.fastly.net
       i:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance CA-3
     1 s:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance CA-3
       i:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance EV Root CA
    ---

This line verify error:num=20:unable to get local issuer certificate makes sure that https://registry.npmjs.org does not pack root certificate. So we Google DigiCert High Assurance EV Root CA root Certificate.

I would use .*. . matches any character, * signifies 0 or more occurrences. You might need a DOTALL switch to the regex to capture new lines with ..

os.path.relpath:

Return a relative filepath to path either from the current directory or from an optional start point.

>>> from os.path import relpath
>>> relpath('/usr/var/log/', '/usr/var')
'log'
>>> relpath('/usr/var/log/', '/usr/var/sad/')
'../log'

So, if relative path starts with '..' - it means that the second path is not descendant of the first path.

In Python3 you can use PurePath.relative_to:

Python 3.5.1 (default, Jan 22 2016, 08:54:32)
>>> from pathlib import Path

>>> Path('/usr/var/log').relative_to('/usr/var/log/')
PosixPath('.')

>>> Path('/usr/var/log').relative_to('/usr/var/')
PosixPath('log')

>>> Path('/usr/var/log').relative_to('/etc/')
Traceback (most recent call last):

What you need to add is a custom HostnameVerifier class bypasses certificate verification and returns true

HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });

This needs to be placed appropriately in your code.

In my case I kept the project on desktop and to access the desktop we need to add permission to the folder so I simply moved my project folder to C:\ directory now its working like a charm.

You can define your own custom MarshalJSON and UnmarshalJSON methods and intentionally control what should be included, ex:

package main

import (
    "fmt"
    "encoding/json"
)

type User struct {
    name string
}

func (u *User) MarshalJSON() ([]byte, error) {
    return json.Marshal(&struct {
        Name     string `json:"name"`
    }{
        Name:     "customized" + u.name,
    })
}

func main() {
    user := &User{name: "Frank"}
    b, err := json.Marshal(user)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(string(b))
}

While it is common for new programmer to make this mistake of performing integer division when they actually meant to use floating point division, in actual practice integer division is a very common operation. If you are assuming that people rarely use it, and that every time you do division you'll always need to remember to cast to floating points, you are mistaken.

First off, integer division is quite a bit faster, so if you only need a whole number result, one would want to use the more efficient algorithm.

Secondly, there are a number of algorithms that use integer division, and if the result of division was always a floating point number you would be forced to round the result every time. One example off of the top of my head is changing the base of a number. Calculating each digit involves the integer division of a number along with the remainder, rather than the floating point division of the number.

Because of these (and other related) reasons, integer division results in an integer. If you want to get the floating point division of two integers you'll just need to remember to cast one to a double/float/decimal.

Series is a one-dimensional labeled array capable of holding any data type (integers, strings, floating point numbers, Python objects, etc.). The axis labels are collectively referred to as the index. The basic method to create a Series is to call:

s = pd.Series(data, index=index)

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table, or a dict of Series objects.

 d = {'one' : pd.Series([1., 2., 3.], index=['a', 'b', 'c']),
 two' : pd.Series([1., 2., 3., 4.], index=['a', 'b', 'c', 'd'])}
 df = pd.DataFrame(d)

If you know exactly which frames to extract, eg 1, 200, 400, 600, 800, 1000, try using:

select='eq(n\,1)+eq(n\,200)+eq(n\,400)+eq(n\,600)+eq(n\,800)+eq(n\,1000)' \
       -vsync vfr -q:v 2

I'm using this with a pipe to Imagemagick's montage to get 10 frames preview from any videos. Obviously the frame numbers you'll need to figure out using ffprobe

ffmpeg -i myVideo.mov -vf \
    select='eq(n\,1)+eq(n\,200)+eq(n\,400)+eq(n\,600)+eq(n\,800)+eq(n\,1000)',scale=320:-1 \
    -vsync vfr -q:v 2 -f image2pipe -vcodec ppm - \
  | montage -tile x1 -geometry "1x1+0+0<" -quality 100 -frame 1 - output.png

.

Little explanation:

1. In ffmpeg expressions + stands for OR and * for AND
2. \, is simply escaping the , character
3. Without -vsync vfr -q:v 2 it doesn't seem to work but I don't know why - anyone?

Assuming Nothing Follows Them

If these two div elements are basically your main layout elements, and nothing follows them in the html, then there is a pure HMTL/CSS solution that takes the normal order shown in this fiddle and is able to flip it vertically as shown in this fiddle using one additional wrapper div like so:

HTML

<div class="wrapper flipit">
   <div id="first_div">first div</div>
   <div id="second_div">second div</div>
</div>

CSS

.flipit {
    position: relative;
}
.flipit #first_div {
    position: absolute;
    top: 100%;
    width: 100%;
}

This would not work if elements follow these div's, as this fiddle illustrates the issue if the following elements are not wrapped (they get overlapped by #first_div), and this fiddle illustrates the issue if the following elements are also wrapped (the #first_div changes position with both the #second_div and the following elements). So that is why, depending on your use case, this method may or may not work.

For an overall layout scheme, where all other elements exist inside the two div's, it can work. For other scenarios, it will not.

\b is a zero-width word boundary. Specifically:

Matches at the position between a word character (anything matched by \w) and a non-word character (anything matched by [^\w] or \W) as well as at the start and/or end of the string if the first and/or last characters in the string are word characters.

Example: .\b matches c in abc

\B is a zero-width non-word boundary. Specifically:

Matches at the position between two word characters (i.e the position between \w\w) as well as at the position between two non-word characters (i.e. \W\W).

Example: \B.\B matches b in abc

I've just tested the following in Chrome (79), Firefox (71) and Edge (44) and it works fine. It applies the script solution as others noted above.

Just add a "Logout" link and when clicked return the following html

    <div>You have been logged out. Redirecting to home...</div>    

<script>
    var XHR = new XMLHttpRequest();
    XHR.open("GET", "/Home/MyProtectedPage", true, "no user", "no password");
    XHR.send();

    setTimeout(function () {
        window.location.href = "/";
    }, 3000);
</script>

It is a very bad idea to get all files in one go, you should rather get it in batches.

One implementation which I use to fetch a particular folder (directory) from S3 is,

def get_directory(directory_path, download_path, exclude_file_names):
    # prepare session
    session = Session(aws_access_key_id, aws_secret_access_key, region_name)

    # get instances for resource and bucket
    resource = session.resource('s3')
    bucket = resource.Bucket(bucket_name)

    for s3_key in self.client.list_objects(Bucket=self.bucket_name, Prefix=directory_path)['Contents']:
        s3_object = s3_key['Key']
        if s3_object not in exclude_file_names:
            bucket.download_file(file_path, download_path + str(s3_object.split('/')[-1])

and still if you want to get the whole bucket use it via CIL as @John Rotenstein mentioned as below,

aws s3 cp --recursive s3://bucket_name download_path

MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package.

To install the MinGW-w64 toolchain (Reference):

1. Open MSYS2 shell from start menu
2. Run pacman -Sy pacman to update the package database
3. Re-open the shell, run pacman -Syu to update the package database and core system packages
4. Re-open the shell, run pacman -Su to update the rest
5. Install compiler:
   • For 32-bit target, run pacman -S mingw-w64-i686-toolchain
   • For 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
6. Select which package to install, default is all
7. You may also need make, run pacman -S make

I noticed downgrading Gradle build tools to 1.2.3 solved my problem of the Crunching PNG error, but on 1.5.0 the problem continues.

On Windows this worked for me:

Add the content of your self signed certificate to the end of the ca-bundle file. Including the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- lines

The location of the ca-bundle file is usually C:\Program Files\Git\mingw64\ssl\certs

Afterwards, add the path of the ca-bundle file to the global git config. The following command does the trick: git config --global http.sslCAInfo "C:/Program Files/Git/mingw64/ssl/certs/ca-bundle.crt"

Remark: The Path depends on your local path of the ca-bundle file!

There is another way to pass multiple ranges to a function, which I think feels much cleaner for the user. When you call your function in the spreadsheet you wrap each set of ranges in brackets, for example: calculateIt( (A1,A3), (B6,B9) )

The above call assumes your two Sessions are in A1 and A3, and your two Customers are in B6 and B9.

To make this work, your function needs to loop through each of the Areas in the input ranges. For example:

Function calculateIt(Sessions As Range, Customers As Range) As Single

    ' check we passed the same number of areas
    If (Sessions.Areas.Count <> Customers.Areas.Count) Then
        calculateIt = CVErr(xlErrNA)
        Exit Function
    End If

    Dim mySession, myCustomers As Range

    ' run through each area and calculate
    For a = 1 To Sessions.Areas.Count

        Set mySession = Sessions.Areas(a)
        Set myCustomers = Customers.Areas(a)

        ' calculate them...
    Next a

End Function

The nice thing is, if you have both your inputs as a contiguous range, you can call this function just as you would a normal one, e.g. calculateIt(A1:A3, B6:B9).

Hope that helps :)

This is an older question with a proper answer (please use parameterized queries) which I'd like to extend with some timezone discussion. For my current project I was interested in how do the datetime columns handle timezones and this question is the one I found.

Turns out, they do not, at all.

datetime column stores the given DateTime as is, without any conversion. It does not matter if the given datetime is UTC or local.

You can see for yourself:

using (var connection = new SqlConnection(connectionString))
{
    connection.Open();
    using (var command = connection.CreateCommand())
    {
        command.CommandText = "SELECT * FROM (VALUES (@a, @b, @c)) example(a, b, c);";

        var local = DateTime.Now;
        var utc = local.ToUniversalTime();

        command.Parameters.AddWithValue("@a", utc);
        command.Parameters.AddWithValue("@b", local);
        command.Parameters.AddWithValue("@c", utc.ToLocalTime());

        using (var reader = command.ExecuteReader())
        {
            reader.Read();

            var localRendered = local.ToString("o");

            Console.WriteLine($"a = {utc.ToString("o").PadRight(localRendered.Length, ' ')} read = {reader.GetDateTime(0):o}, {reader.GetDateTime(0).Kind}");
            Console.WriteLine($"b = {local:o} read = {reader.GetDateTime(1):o}, {reader.GetDateTime(1).Kind}");
            Console.WriteLine($"{"".PadRight(localRendered.Length + 4, ' ')} read = {reader.GetDateTime(2):o}, {reader.GetDateTime(2).Kind}");
        }
    }
}

What this will print will of course depend on your time zone but most importantly the read values will all have Kind = Unspecified. The first and second output line will be different by your timezone offset. Second and third will be the same. Using the "o" format string (roundtrip) will not show any timezone specifiers for the read values.

Example output from GMT+02:00:

a = 2018-11-20T10:17:56.8710881Z      read = 2018-11-20T10:17:56.8700000, Unspecified
b = 2018-11-20T12:17:56.8710881+02:00 read = 2018-11-20T12:17:56.8700000, Unspecified
                                      read = 2018-11-20T12:17:56.8700000, Unspecified

Also note of how the data gets truncated (or rounded) to what seems like 10ms.

If you mean what ports are listening, you can open a command prompt and write:

netstat

You can write:

netstat /?

for an explanation of all options.

As documented here create-react-app will only import environment variables beginning with REACT_APP_, so the PUBLIC_URL, I believe, as mentioned by @redbmk, comes from the homepage setting in the package.json file.

plainText = raw_input("What is your plaintext? ")
shift = int(raw_input("What is your shift? "))

def caesar(plainText, shift): 
    for ch in plainText:
        if ch.isalpha():
            stayInAlphabet = ord(ch) + shift 
            if stayInAlphabet > ord('z'):
                stayInAlphabet -= 26
            finalLetter = chr(stayInAlphabet)
        #####HERE YOU RESET CIPHERTEXT IN EACH ITERATION#####
        cipherText = ""
        cipherText += finalLetter

    print "Your ciphertext is: ", cipherText

    return cipherText

caesar(plainText, shift)

As an else to if ch.isalpha() you can put finalLetter=ch.

You should remove the line: cipherText = ""

Cheers.

select to_number(exception_value) from exception where to_number(exception_value) = 105

You can just declare a regular array like so:

var arry = [];

Then when you have a pair of values to add to the array, all you need to do is:

arry.push([value_1, value2]);

And yes, the first time you call arry.push, the pair of values will be placed at index 0.

From the nodejs repl:

> var arry = [];
undefined
> arry.push([1,2]);
1
> arry
[ [ 1, 2 ] ]
> arry.push([2,3]);
2
> arry
[ [ 1, 2 ], [ 2, 3 ] ]

Of course, since javascript is dynamically typed, there will be no type checker enforcing that the array remains 2 dimensional. You will have to make sure to only add pairs of coordinates and not do the following:

> arry.push(100);
3
> arry
[ [ 1, 2 ],
  [ 2, 3 ],
  100 ]

The object viewer in Acrobat is good but Windjack Solution's PDF Canopener allows better inspection with an eyedropper for selecting objects on page. Also permits modifications to be made to PDF.

open ~/.bash_profile and add these bash functions to the end of the file

function androidinstall(){
   adb install -r ./bin/$1.apk
}
function androidrun(){
   ant clean debug
   adb shell am start -n $1/$1.$2
}

then open the Android project folder

androidinstall app-debug && androidrun com.example.app MainActivity

This also works (and I find it a tiny bit easier to remember)

command 2> /dev/fd/1 | grep 'something'

More info about /dev/fd directory here

The directory or a file in it is locked and cannot be deleted. Find the culprit who locks it and see if you can eliminate it.

Needle module is also good, here is an example which uses needle module

var needle = require('needle');

needle.get('http://www.google.com', function(error, response) {
  if (!error && response.statusCode == 200)
    console.log(response.body);
});

To add an Activity using Android Studio.

This step is same as adding Fragment, Service, Widget, and etc. Screenshot provided.

[UPDATE] Android Studio 3.5. Note that I have removed the steps for the older version. I assume almost all is using version 3.x.

1. Right click either java package/java folder/module, I recommend to select a java package then right click it so that the destination of the Activity will be saved there
2. Select/Click New
3. Select Activity
4. Choose an Activity that you want to create, probably the basic one.

To add a Service, or a BroadcastReceiver, just do the same step.

Previous versions did not really work with sections > 1. So my solution was found here https://codentrick.com/create-a-tag-flow-layout-with-uicollectionview/. For the lazy ones:

override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? {
    let attributesForElementsInRect = super.layoutAttributesForElements(in: rect)
    var newAttributesForElementsInRect = [UICollectionViewLayoutAttributes]()
    // use a value to keep track of left margin
    var leftMargin: CGFloat = 0.0;
    for attributes in attributesForElementsInRect! {
        let refAttributes = attributes 
        // assign value if next row
        if (refAttributes.frame.origin.x == self.sectionInset.left) {
            leftMargin = self.sectionInset.left
        } else {
            // set x position of attributes to current margin
            var newLeftAlignedFrame = refAttributes.frame
            newLeftAlignedFrame.origin.x = leftMargin
            refAttributes.frame = newLeftAlignedFrame
        }
        // calculate new value for current margin
        leftMargin += refAttributes.frame.size.width + 10
        newAttributesForElementsInRect.append(refAttributes)
    }

    return newAttributesForElementsInRect
}

No, because Strings in Java are immutable. You'll have to create a new string removing the character you don't want.

For replacing a single char c at index position idx in string str, do something like this, and remember that a new string will be created:

String newstr = str.substring(0, idx) + str.substring(idx + 1);

First, array_length should be an integer and not a string:

array_length = len(array_dates)

Second, your for loop should be constructed using range:

for i in range(array_length):  # Use `xrange` for python 2.

Third, i will increment automatically, so delete the following line:

i += 1

Note, one could also just zip the two lists given that they have the same length:

import csv

dates = ['2020-01-01', '2020-01-02', '2020-01-03']
urls = ['www.abc.com', 'www.cnn.com', 'www.nbc.com']

csv_file_patch = '/path/to/filename.csv'

with open(csv_file_patch, 'w') as fout:
    csv_file = csv.writer(fout, delimiter=';', lineterminator='\n')
    result_array = zip(dates, urls)
    csv_file.writerows(result_array)

I always just convert a matrix:

x <- as.data.frame(matrix(nrow = 100, ncol = 10))

First of all, you don't need to "clean up" strings and ints - they will be taken care of automatically by the garbage collector. The only thing that needs to be cleaned up in Dispose are unmanaged resources or managed recources that implement IDisposable.

However, assuming this is just a learning exercise, the recommended way to implement IDisposable is to add a "safety catch" to ensure that any resources aren't disposed of twice:

public void Dispose()
{
    Dispose(true);

    // Use SupressFinalize in case a subclass 
    // of this type implements a finalizer.
    GC.SuppressFinalize(this);   
}
protected virtual void Dispose(bool disposing)
{
    if (!_disposed)
    {
        if (disposing) 
        {
            // Clear all property values that maybe have been set
            // when the class was instantiated
            id = 0;
            name = String.Empty;
            pass = String.Empty;
        }

        // Indicate that the instance has been disposed.
        _disposed = true;   
    }
}

Actually, technically when indented properly, it would be:

if (condition) {
    ...
} else {
    if (condition) {
        ...
    } else {
        ...
    }
}

There is no else if, strictly speaking.

(Update: Of course, as pointed out, the above is not considered good style.)

In case someone else is brought here by google because they were trying to use a variable for a method within a class, the below is a code sample which will actually work. None of the above worked for my situation. The key difference is the & in the declaration of $c = & new... and &$c being passed in call_user_func.

My specific case is when implementing someone's code having to do with colors and two member methods lighten() and darken() from the csscolor.php class. For whatever reason, I wanted to have the same code be able to call lighten or darken rather than select it out with logic. This may be the result of my stubbornness to not just use if-else or to change the code calling this method.

$lightdark="lighten"; // or optionally can be darken
$color="fcc";   // a hex color
$percent=0.15;  
include_once("csscolor.php");
$c = & new CSS_Color($color);
$rtn=call_user_func( array(&$c,$lightdark),$color,$percent);

Note that trying anything with $c->{...} didn't work. Upon perusing the reader-contributed content at the bottom of php.net's page on call_user_func, I was able to piece together the above. Also, note that $params as an array didn't work for me:

// This doesn't work:
$params=Array($color,$percent);
$rtn=call_user_func( array(&$c,$lightdark),$params);

This above attempt would give a warning about the method expecting a 2nd argument (percent).

I had the same issue to remove old fragments. I ended up clearing the layout that contained the fragments.

LinearLayout layout = (LinearLayout) a.findViewById(R.id.layoutDeviceList);
layout.removeAllViewsInLayout();
FragmentTransaction ft = getFragmentManager().beginTransaction();
...

I do not know if this creates leaks, but it works for me.

I think using md5 or sha256 or any hash optimized for speed is perfectly fine and am very curious to hear any rebuttle other users might have. Here are my reasons

1. If you allow users to use weak passwords such as God, love, war, peace then no matter the encryption you will still be allowing the user to type in the password not the hash and these passwords are often used first, thus this is NOT going to have anything to do with encryption.

2. If your not using SSL or do not have a certificate then attackers listening to the traffic will be able to pull the password and any attempts at encrypting with javascript or the like is client side and easily cracked and overcome. Again this is NOT going to have anything to do with data encryption on server side.

3. Brute force attacks will take advantage weak passwords and again because you allow the user to enter the data if you do not have the login limitation of 3 or even a little more then the problem will again NOT have anything to do with data encryption.

4. If your database becomes compromised then most likely everything has been compromised including your hashing techniques no matter how cryptic you've made it. Again this could be a disgruntled employee XSS attack or sql injection or some other attack that has nothing to do with your password encryption.

I do believe you should still encrypt but the only thing I can see the encryption does is prevent people that already have or somehow gained access to the database from just reading out loud the password. If it is someone unauthorized to on the database then you have bigger issues to worry about that's why Sony got took because they thought an encrypted password protected everything including credit card numbers all it does is protect that one field that's it.

The only pure benefit I can see to complex encryptions of passwords in a database is to delay employees or other people that have access to the database from just reading out the passwords. So if it's a small project or something I wouldn't worry to much about security on the server side instead I would worry more about securing anything a client might send to the server such as sql injection, XSS attacks or the plethora of other ways you could be compromised. If someone disagrees I look forward to reading a way that a super encrypted password is a must from the client side.

The reason I wanted to try and make this clear is because too often people believe an encrypted password means they don't have to worry about it being compromised and they quit worrying about securing the website.

UPDATE: I suggest using a solution with filters, provided by @Jess.

I would write a method for that, and then where you need to format price you can just put the method in the template and pass value down

methods: {
    formatPrice(value) {
        let val = (value/1).toFixed(2).replace('.', ',')
        return val.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".")
    }
}

And then in template:

<template>
    <div>
        <div class="panel-group"v-for="item in list">
            <div class="col-md-8">
                <small>
                   Total: <b>{{ formatPrice(item.total) }}</b>
                </small>
            </div>
        </div>
    </div>
</template>

BTW - I didn't put too much care on replacing and regular expression. It could be improved.enter code here

Vue.filter('tableCurrency', num => {_x000D_
  if (!num) {_x000D_
    return '0.00';_x000D_
  }_x000D_
  const number = (num / 1).toFixed(2).replace(',', '.');_x000D_
  return number.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ',');_x000D_
});

You have to be specific about the columns you are selecting. If your user table had four columns id, name, username, opted_in you must select exactly those four columns from the query. The syntax looks like:

INSERT INTO user (id, name, username, opted_in)
  SELECT id, name, username, opted_in 
  FROM user LEFT JOIN user_permission AS userPerm ON user.id = userPerm.user_id

However, there does not appear to be any reason to join against user_permission here, since none of the columns from that table would be inserted into user. In fact, this INSERT seems bound to fail with primary key uniqueness violations.

MySQL does not support inserts into multiple tables at the same time. You either need to perform two INSERT statements in your code, using the last insert id from the first query, or create an AFTER INSERT trigger on the primary table.

INSERT INTO user (name, username, email, opted_in) VALUES ('a','b','c',0);
/* Gets the id of the new row and inserts into the other table */
INSERT INTO user_permission (user_id, permission_id) VALUES (LAST_INSERT_ID(), 4)

Or using a trigger:

CREATE TRIGGER creat_perms AFTER INSERT ON `user`
FOR EACH ROW
BEGIN
  INSERT INTO user_permission (user_id, permission_id) VALUES (NEW.id, 4)
END

If you don't need to support IE9 or lower, you can use flexbox freely, and don't need to use floated layouts.

It's worth noting that today, the use of floated elements for layout is getting more and more discouraged with the use of better alternatives.

• display: inline-block - Better
• Flexbox - Best (but limited browser support)

Flexbox is supported from Firefox 18, Chrome 21, Opera 12.10, and Internet Explorer 10, Safari 6.1 (including Mobile Safari) and Android's default browser 4.4.

For a detailed browser list see: https://caniuse.com/flexbox.

(Perhaps once its position is established completely, it may be the absolutely recommended way of laying out elements.)

A clearfix is a way for an element to automatically clear its child elements, so that you don't need to add additional markup. It's generally used in float layouts where elements are floated to be stacked horizontally.

The clearfix is a way to combat the zero-height container problem for floated elements

A clearfix is performed as follows:

.clearfix:after {
   content: " "; /* Older browser do not support empty content */
   visibility: hidden;
   display: block;
   height: 0;
   clear: both;
}

Or, if you don't require IE<8 support, the following is fine too:

.clearfix:after {
  content: "";
  display: table;
  clear: both;
}

Normally you would need to do something as follows:

<div>
    <div style="float: left;">Sidebar</div>
    <div style="clear: both;"></div> <!-- Clear the float -->
</div>

With clearfix, you only need the following:

<div class="clearfix">
    <div style="float: left;" class="clearfix">Sidebar</div>
    <!-- No Clearing div! -->
</div>

You have a view model to which your view is strongly typed => use strongly typed helpers:

<%= Html.DropDownListFor(
    x => x.SelectedAccountId, 
    new SelectList(Model.Accounts, "Value", "Text")
) %>

Also notice that I use a SelectList for the second argument.

And in your controller action you were returning the view model passed as argument and not the one you constructed inside the action which had the Accounts property correctly setup so this could be problematic. I've cleaned it a bit:

public ActionResult AccountTransaction()
{
    var accounts = Services.AccountServices.GetAccounts(false);
    var viewModel = new AccountTransactionView
    {
        Accounts = accounts.Select(a => new SelectListItem
        {
            Text = a.Description,
            Value = a.AccountId.ToString()
        })
    };
    return View(viewModel);
}

s = s.rstrip()

will remove all newlines at the end of the string s. The assignment is needed because rstrip returns a new string instead of modifying the original string.

A really easy way to do it is to create an ODBC link in EXCEL and run SP_WHO2 from there.

You can Refresh whenever you like and because it's EXCEL everything can be manipulated easily!

Do whatever you want to do after the file loads successfully.just after the completion of your file processing set the value of file control to blank string.so the .change() will always be called even the file name changes or not. like for example you can do this thing and worked for me like charm

  $('#myFile').change(function () {
    LoadFile("myFile");//function to do processing of file.
    $('#myFile').val('');// set the value to empty of myfile control.
    });

When publishing to IIS, by Web Deploy, I just checked the File Publish Options and executed. Now it works! After this deploy the checkboxes do not need to be checked. I don't think this can be a solutions for everybody, but it is the only thing I needed to do to solve my problem. Good luck.
